e-SENSE

The management of monitoring of equipment isincreasingly done remotely at a (considerable)distance. Configuration, reading and, ifnecessary, taking action on data received from aremote location of one’s choice are possibilitiesthat are nowadays standard requirements.

You can do a lot more than just measure withthe e-SENSE® telemetry measuring system, wheremeasurement data is collected by intelligentsensors such as the e+®-sensors or the Diver®.Intelligent sensors independently measure datain the field and save them internally.

Your measurements or alarm signals are sent toa database in your own PC (e-SENSE direct) viathe connection with the e-SENSE field modem.

Province of Gelderland / Vitens: automated measuring networkIn the fully-automated primary groundwater level measuring network of theProvince of Gelderland and the secondary measurement systems around thegroundwater withdrawal holes of water supply company VITENS, thegroundwater level is measured every 3 hours by Divers®. Collecting informationon the groundwater system in a systematic way is necessary to manage thegroundwater well. Each province is therefore obliged to set up a measuringnetwork for groundwater: this measuring network comprises more than 400measurement locations. From 1998, daily readouts were taken at 16 of theselocations using telemetry. Of these 16 locations, 6 or 7 have since been fittedwith an e-SENSE module. With a Diver integrated into the e-SENSE system,Vitens always has all the values at its disposal without being dependent for thison access to a certain location.

Artesia: Water infiltration against dryingWater supply company Evides and the Province of North Brabant hired Artesiaconsultancy to support the implementation of a trial project for infiltration.Water supply company Evides wanted preferably to use groundwater for thepreparation of drinking water in the Southwest Netherlands. It concerned atrial that had to show whether water infiltration was an effective tool againstdrying.9 e+ SOIL MCT sensors, supplied by Eijkelkamp, monitored the infiltration fromthe infiltration reservoirs by measuring moisture content. Moreover, 24 Divers,supplied by Eijkelkamp, were used to measure the temperature and the waterlevel. All sensors under the infiltration water were fitted with a readout cableat the edge of the infiltration reservoirs.This project was an interesting application of the multi-functional e+ SOIL MCT.This soil moisture, conductivity and temperature sensor saves the measureddata internally and can pass it on to the user via the e-SENSE telemetry systemor send it directly to the readout unit or PC.

e-SENSE direct Open Interface as optionBy using a modern standardised SQL database system, e-SENSE direct gets anOpen Interface that ensures that the system can be linked easily and cheaplywith standard components to other software systems such as SCADA. In thisway, SCADA systems can use all the unique facilities of e-SENSE direct such asPlug & Play when changing configurations in the field. In addition, there is alsothe option of activating the e-SENSE direct user interface for specific functionsthat one does not wish to integrate into the SCADA systems.

e-SENSE directe-SENSE direct is easy to install (Plug & Play), to manage and to maintain. Withe-SENSE direct, you can manage and communicate with your sensors fromyour PC. You have an overview over the whole installation and you can changeall the settings. This allows you to operate the system optimally with respect toresponse speed, data traffic costs and the use of batteries. The measurementscan be imported into the Logger Data Manager (LDM) e+ software, after whichthey can be processed, e.g. into graphical representations and reports.You can also export the data to your own personal database.


TNO-NITG: predicting groundwater levels and soil moistureprofilesSome time ago, TNO-NITG performed a pilot project that followed thegroundwater and soil moisture situation on a daily basis and tested this againstthe desired situation. In addition, it predicted online the groundwater levelsand soil moisture profiles for the coming five to ten days. This resulted in a toolto curb the geohydrological risks in advance.The trial set-up comprised one automatic groundwater level meter – the‘Diver’- and five e+ SOIL MCT sensors. They were able to make the most currentsituation overseeable, so that it could serve as the basis for the prediction. Eachday, the Eijkelkamp e-SENSE SMS-modem sends the latest measurements bySMS to the central data server. In this way, the latest measurements were athand to make the best prediction. If you compare this measurement methodwith the traditional manual measurement method, the high measurementfrequency and the rapid availability of the data of the e-SENSE-system wasnotably in favour of the new method.

Arcadis: prevention of floods in RomaniaIn the winter months, a mountainous region of Romania suffers fromconsiderable flooding. This problem was tackled by Arcadis. Part of the projectconcerned setting up a monitoring network, so that timely measures could betaken in times of high water. At this point, Eijkelkamp came into the picturewith its e-SENSE modems, Diver® and the e+ RAIN sensors. With theinstallation of 5 e-SENSE measuring stations, one hopes to get a better insightin the future into the behaviour of the rivers. Through this project, one alsohopes in the future to in any case easily change the measuring frequency fromone’s PC in times of heavy rainfall and during a risk of flooding. If desired, themost recent water levels can be viewed and measures can be taken basedupon them, e.g. the evacuation of the population from the areas threatenedby flooding.

e-SENSE communication by sending data via SMSThe decision was taken to use a GSM/SMS-network. The reason for this wasthat the GSM-network now has an almost world encompassing range. Datacommunication by SMS is relatively inexpensive and the expectations are thatprices will fall further in the near future. As far as this is concerned, this systemdistinguishes itself from other commonly used systems. Communication withthese systems occurs via GSM-networks that depend on interaction betweenthe sending and receiving modem.

The e-SENSE system generates an alarmSuch interaction always demands the full availability of the connection and thereceiving modem. Substantial costs are associated with both the equipmentand the communication with this way of working. The right alternative is SMS(short message service), a service that almost all GSM providers offer. Themeasurements from the connected intelligent sensors are read out and sent asSMS-code to the database. Very little data traffic is required for such messagesand this is why it is cheap..

Limburg Water Board (WML): providing drinking waterTo ‘save’ scarce groundwater, WML increasingly takes drinking water fromMaas water. Modern technology makes drinking water from Maas water thatsatisfies the most stringent quality requirements and tastes good. WML startedafter lengthy research with the purchase of 10 Divers. This has since grown tono less than 900. At the end of 2000, it was decided that an increased numberof parameters and the faster retrieval of data from the Diver was necessary forWML and attention was given here in particular to further time saving. For this,telemetry appeared to be the solution and e-SENSE the system.

Zeeland Islands Water Board: optimisation of measuringnetwork with e+ WATER LIn 2005, Zeeland Islands Water Board decided to further optimise its measuringnetwork with Divers with 50 extra measuring points with e+ WATER L sensors.Because it related to data that would be used in calculations, the water boarddid not think it necessary to put the data directly online. Zeeland Islands chosethe e+ WATER L, as these sensors have internal air pressure compensation andbecause the whole package of delivery, installation and service was offered byone company: Eijkelkamp.

Two-way communicationWith e-SENSE, two-way communication is possible between the measuringelement in the field and the central computer system. The data is sent from thesensor to the database. The settings of the sensors in the field can easily bechanged from your workstation. Increasing or reducing the measuring intervalis easy and one does not need to go to the measuring locations oneself. Onecan also download the documents in the LDM software and in ASCII-format(using spreadsheets).

This device fits in the palm of your hand and is surprisingly lightweight.With a length of only 90 mm (183 mm for the CTD-Diver) and a diameter of 22mm (18 mm for the MicroDriver), the Diver can be used in almost everymonitoring well. The pressure sensor, the conductivity sensor and the datalogger and its battery are all placed in a hermetically sealed stainless steel orceramic housing. This ensures that the Diver is less sensitive to moisture orexternal electric influences (Faraday cage). The Diver can easily be placed in amonitoring well by hanging it up on a steel or vectran wire.

The Diver is available in various designs:The MiniDiver®: a stainless steel housing and a ceramic pressure sensor,diameter 22 mm, length 90 mm, available for different measuring ranges,memory capacity 24,000 measurements.The MicroDiver®: a stainless steel housing, a ceramic pressure sensor,diameter 18 mm, length 90 mm, available for different measuring ranges,memory capacity 48,000 measurements.The CeraDiver®: a ceramic housing, a ceramic pressure sensor,diameter 22 mm, length 90 mm, available for different measuring ranges,memory capacity 48,000 measurements.The CTD-Diver®: ®: a ceramic housing, a ceramic pressure sensor and aplatinum ceramic conductivity sensor (measuring range 0 – 80 mS/cm), diameter22 mm, length 183 mm, available for different measuring ranges, memorycapacity 16,000 measurements.The Baro-Diver®: the function of the Barodiver is to record atmosphericpressure. It can quickly and easily compensate for variations with the softwareof the Logger Data Manager (LDM).

Cables

Communication cablesThere are two different types of cables: Communication cables to connect e+sensors to the SMS-modem, varying in length from 1 to 200 metres, with anIP68-connector for watertight connections. Communication cables to connectDivers to the SMS-modem, varying in length from 1 to 200 metres, with anIP68-connector for watertight connections.

Readout and communication

The readout and configuring of the e+ sensors or Divers can occur in differentways:• Through the e-SENSE-modem, via the software of e-SENSE direct or LDM

(Logger Data Manager).• With an infrared readout device that is used if the e+sensor or Diver is placed

in the immediate vicinity of a PC (Laptop).

If the e+ sensors or Divers are used as stand alone applications, the following accessories can be used:• A Diver Data Cable, available in different lengths of up to 200 m (only for

Divers) to read the sensors manually.• An IrDa-readout unit. These are meant for the readout of the measurements

from the e+ sensor or Diver using a laptop computer.This can occur at a distance of 1 or 2 metres from the e+ sensor.For this, the IrDa-readout unit must be aimed at the infraredLEDs on the side of the e+sensor.

Optional accessories

Finally, various optional accessories are available, such as field supports andaugers for the installation of e+ SOIL MCT sensors.
